I have last years Premier as well. I picked it up late last season and then also picked up some C60's. While I am sure those would work well I am considering selling those. Looking at Ride SPI, Doulbe Agent or CAD as most likely candidates. Other options would be Rome Targa (or older Arsenal, they softened up this year, aforementioned C60's or CO2's, or Flux stiffer model (DMCC for this year?)
